Surface Preparation
| Substrate | Minimum | Recommended |
| Carbon Steel | St 2 (ISO 8501-1) | Sa 2½ (ISO 8501-1) |
| Stainless steel | The surface should be mechanically abraded with non-metallic abrasive or a fibre machine | “Blast clean using an approved non-metallic abrasive |
| to form a scratch profile of at least 45 µm on the surface | to produce a sharp angular surface profile.” |
or to remove the glossy surface.
| Aluminium | The surface should be blasted with a non-metallic abrasive, | “Blast clean using an approved non-metallic abrasive |
| hand- or machine-sanded using abrasive paper or fibre discs, | to produce a sharp angular surface profile.” |
to produce scratch marks on the surface.
| Galvanised steel | The surface should be clean and dry with suitable roughness | |
| Shop-primed Steel | Sa 2 (ISO 8501-1) | |
| Coated surface | A clean, dry and sound compatible primer. | |
| Composite | Polyester-based composites must be fully cured before surface preparation. | |
| The surface should be abraded by hand or machine using a non-metallic abrasive, fibre discs or abrasive paper to produce scratch marks. | ||
| Wood | A clean, dry surface. Contaminants may be removed by washing with cleaner and clean water. | |
The recommended surface preparation provides optimum properties including adhesion, corrosion resistance, heat resistance and chemical resistance.
This product may be applied by the following methods
| Spray: | Use air spray or airless spray. Ensure the specified dry film thickness is achieved. |
| Brush: | Recommended for touch-up and small-area application. Take care to achieve the specified dry film thickness. |
| Roller application | May be used for small areas. Not recommended for the first primer coat. Ensure the specified dry film thickness is achieved. |

For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
